The chapter on Linnaeus as a zoologist was contributed by Dr. William Healey Dall as a part of the same memorial exercises. The chapter on Linnaeus as an evolutionist was published by Dr. Greene in the Proceed- ings of the Washington Academy of Sciences, Vol. XI, March 31, 1909. The two addresses and the special paper are all here printed in the form in which they were originally presented and practically without revision. It may be doubted if any naturalist has exerted a greater influence in the world than has Linnaeus certainly none other has given to the study of animals and plants an impetus so far-reaching or so long-sustained. Whatever we may claim to have been accomplished by those naturalists who preceded him, we must admit that to Linnaeus we owe the essential features of our present system of naming the various species of animals and plants, and it is not too much to say that Linnaeus is the father of systematic zoology and botany. The personality, the biography, of one who hasdone great things in the world is always interesting. The study of the lives of such men is one of the most potent factors in moulding the life of the student, filling it with clean ambitions and leading to right thinking and rational living. Professor Greene has told the story of the life of the great Swede in a way that will prove not only entertaining and instructive to all who are interested in Nature, but also in language delightful in its simplicity and literary charm. BARTON WARREN EVERMANN. LINEAGE AND CHILDHOOD OF LINNAEUS THE personality of Linnaeus and his luminous career as a scientific man make a topic much too large to be presented even in mere outline within the limits of an hour. If this were an assemblage of botanists exclusively, still would the time be too short for the worthy consideration, not only of Linnaeus as a botanist in general, but of his services to any one only of the several departments of the science which it is his glory greatly to have advanced. But then a botanist, a very great botanist, he was also much more than that. I have a fancy it may be more and deeper than a fancy that a great man in whatsoever profession, a man of power in any branch of science, is greater than the science to which he devotes himself that he himself personally is of more moment, and ought to be of deeper interest than his science yes, than all the sciences that are or ever shall be...
